COATING COMPOUND.

To all whom. it may concern:

Be it known that I, THOMAS E. CONWAY,

a citizen of the United States, residing at The invention relates toacomposition of matter, and more particularly to an improved coatingcompound.

The prime function of the invention is to protect conduits, mains,pipes, and other like leads used in conveying gas or other fluid forpreservation against the action of acld and alkaline properties presentin thefluid when flowing through the same, thereby increasing the lifeof such conduits, pipes or the like. I

A further'function of the invention is the provision of a coatingcompound of the character described which will impregnate the pores of aconduit, pipe or the like, which is subjected to electric currents sothat the same is rendered impervious to all kinds of acid properties oralkaline waters, thus obviating electrolysis, rust or crumbling away ofsuch conduit, pipe or the like when in use. I

The composition consists of the following ingredients, combined in theproportions stated, viz:

predetermined Fahrenheit temperature. Also the article to which thecompound thus treated is to be applir d is subjected to a pre-Specification of Letters Patent. Application filed August 3, 1910.Serial No. 575,376.

Patented Mar. 19, 1912.

determined temperature of heat, prior to the application of the saidcompound. It will be herein stated that this compound differs from apaint composition, because it is an impossibility to apply the same towood material. Furthermore, it difi'ers in that the article and also thecompound have to be subjected to heat prior to the application of thecomposition of matter on the said article. The composition when appliedto the article to be coated, will penetrate the pores thereof so as tomake the said article impervious to water, and also making it proof aainst all kinds of alkaline waters, rust an electrolysis.

It is, of course, to be understood that in the application of thecomposition, the latter must be applied immediately when the same hasbeen heated to a predetermined temperature and likewise the article tobe coated therewith.

What is claimed is;

The herein-described composition of matter for coating and filling thepores of conduits, pipes, mains or the like, consisting of ironsesquioxid 2.57%; lead carbonate 10.74%; zinc oxid 8.36%; copper oxid8.12%; and ordinary commercial itch 70.21%, forming a water, acid and alaliproof, electric-insulating compound thick and incapable of beingspread at normal temperature, adapted to be thinned at high temperatureand of a consistence and degree of refractability requiring both it andthe article to be heated in the coating process, substantially asdescribed.

In testimon whereof I afiix my signature inpresence 0 two witnesses.
